Hybrid testing of lumbar CHARITE discs versus fusions.

STUDY DESIGN An in vitro human cadaveric biomechanical study. OBJECTIVES To quantify effects on operated and other levels, including adjacent levels, due to CHARITE disc implantations versus simulated fusions, using follower load and the new hybrid test method in flexion-extension and bilateral torsion. SUMMARY OF BACKGROUND DATA Spinal fusion has been… CONTINUE READING
